HAZARDOUS MATERIAL REPORT (HMR)
A hazardous material report (HMR) is a standard
method to report material deficiencies that, if not
corrected, could cause death or injury to personnel, loss
of aircraft, or damage to equipment or facilities. An
HMR priority precedence message should be submitted
within 24 hours of discovery when one or more of the
following conditions occur:
A malfunction or failure of a component part
occurs, that if not corrected, could result in death
or injury to personnel, or damage to or loss of
aircraft, equipment or facilities.
A configuration deficiency (when discovered)
that constitutes a safety hazard in aeronautical
equipment (aircraft, SE, or components) is
Urgent action or assistance is required and
corrective action must be completed at an early
date because of operational commitments.
A design is detected that would allow incorrect
installation of parts, resulting in possible system
malfunction or failure.
A potential or experienced in-flight or on-the-
ground loss of aircraft parts occurs in which a
maintenance or material factor is involved.
"Things Falling Off Aircraft (TFOA)" is the
terminology that is used in reference to an inci-
dent such as when foreign object damage (FOD)
to an engine causes the engine to shed its parts.
QUALITY DEFICIENCY REPORT (QDR)
A quality deficiency report (QDR) reports a
deficiency in new or newly reworked material that may
indicate nonconformance with a contract, a deviation
from a specification requirement, or substandard
workmanship. Definitions of new and reworked
material are as follows:
New material is material that is procured under
contract from industry or is manufactured by an
in-house facility and is under warranty.
Material, whether in actual operation or on the
shelf, is considered new until the warranty
Reworked material is material that has been
overhauled, rebuilt, repaired, or modified by
government or commercial activities but is
unproven in actual operations.
A QDR is targeted toward reporting possible
deficiencies in QA during the manufacturing or rework
process. A discrepancy that is found after initial use of
equipment does not qualify for QDR reporting. Product
Quality Deficiency Report Program, SECNAVINST
4855.5, and Product Data Reporting and Evaluation
Program (PDREP), SECNAVINST 4855.3, provide
overall Navy QDR policy.
Category 1 (CAT 1) QDR
A CAT 1 QDR is used for quality deficiencies that
may cause death, injury, or severe occupational illness.
A CAT 1 QDR is also used for a deficiency that would
cause loss of or major damage to a weapon system;
would critically restrict the combat readiness
capabilities of the using organization; or would result in
a production line stoppage. Unless a CAT 1 QDR is
combined with an HMR, a CAT 1 QDR should be
submitted by routine precedence message within 1
working day after its discovery.
Category 2 (CAT 2) QDR
A CAT 2 QDR is used for quality deficiencies that
have been assessed to have significant and widespread
material or human resource impact but do not affect
safety of personnel or impair combat efficiency. A
CAT 2 QDR is submitted by using the Product Quality
Deficiency Report, Standard Form 368, within 5
working days after discovery of the deficiency.
AIRCRAFT DISCREPANCY REPORT
An aircraft discrepancy report (ADR) identifies
and documents a defect in newly manufactured,
modified, or reworked aircraft to ensure quality
maintenance or rework procedures. An ADR is
documented on Standard Form 368.
An acceptance flight is performed and a functional
check flight (FCF) is flown as soon as possible after the
aircraft is delivered and prior to maintenance. Only
those discrepancies noted by the ferry pilot and those
found during the acceptance inspection and check
flight that can be attributed to the manufacture,
modification, or rework process are on an initial ADR.
